Title: Method of separating and recovering carbon dioxide from gaseous mixtures
IPC: C01B32/50
Filed: 1958-10-22
Abstract: <PICT:0886346/III/1> CO2 is recovered from solutions of alkali metal, or ammonium, carbonates, phosphates, borates, or phenates activated by the presence of arsenious anhydride, which have been employed to absorb the CO2 from gas mixtures, by treating the solution at higher temperature with inert gas (including air), or by the steam inherently generated, at super-atmospheric pressure, the temperatures being above the boiling point of the solution at atmospheric pressure.  Gases containing CO2 are contacted with the absorption solution in absorber 1 which may be operated at elevated temperatures or pressures, if desired.  The exhausted solution is removed from the bottom of the tower and passed through heat-exchanger 2 into regeneration tower 3.  Regeneration is carried out at superatmospheric pressure by heating the solution, e.g. to 180 DEG C., by steam coil 4.  Expelled CO2 issues from the tower at 5, and regenerated solution passes from the bottom of the tower through heat-exchanger 2, and is recycled thence through water cooler 6 to absorption tower 1 by pump 7. Coal gas or N2/H2 mixtures may be used as desorption gases.  Specifications 798,856 and 857,960 are referred to.

Filed: 1966-07-28
Abstract: 1,113,588. Traveller for ring-spinning. TEXTILE & CHEMICAL RESEARCH CO. (VADUZ) Ltd. 28 July, 1966 [28 July, 1965], No. 34017/66. Heading D1D. A traveller for ring- spinning &c., that is particularly useful for preventing fraying when doubling stiff glass filaments that have been coated with bonding-agent that is readily removable, is provided with a roller for guiding the yarn on its path to the winding spool. The roller may be arranged internally or externally of the traveller; it may be arranged at the upper, lower, or middle region of the traveller; it may be mounted on a bracket integrally moulded with or fixed to the traveller. It may be mounted on the traveller itself or on a bracket by a hinge or ball device so that the roller is able to orientate itself automatically e.g. between two extreme positions corresponding to the commencement and termination of the wind. In a preferred form, the roller is mounted in a bracket 12 fixed by a bolt 13 to the traveller. In this case, the traveller being fixed and incapable of orienting itself, is so arranged that the plane of symmetry of the roller perpendicular to its axis, bisects the angle formed by two planes each passing through short segments of yarn upstream and downstream of the roller, in the one case at the start, and in the other at the end of the wind. The traveller is C-shaped and has inclined outer faces 4, 5. The roller, which is carried by a screw-theaded bolt 10, has lateral flanges inclined at an angle which is greater than or equal to that assumed by the yarn travelling over the roller. Between the flanges is a groove of greater radius of curvature than the radius of the yarn.

Title: Improved manufacture of esters and thio esters substituted in the acid residue
Filed: 1932-12-01
Abstract: Esters, including thioesters which are stated to have emulsifying properties are prepared from hydroxy or mercapto fatty acids which contain at least six carbon atoms and are alkylated, cycloalkylated, aralkylated or arylated at the hydroxy or mercapto group, and hydroxy or mercapto aliphatic compounds containing less than six carbon atoms.  In place of the free acids, their functional or substitution derivatives may be employed, for example their halides, anhydrides, esters or halogen, hydroxy, sulphonic or carboxy derivatives.  Basic residues may also be present.  Similarly, reactive derivatives of the hydroxy compounds may be used such as their mineral acid esters, ester salts or alcoholates or their halogen, ether, sulphonic or other substitution derivatives.  In examples: (1) a -bromlauric acid is treated with phenol in the presence of alcohol and caustic soda and the sodium salt of the resulting acid acidified with hydrochloric acid and extracted with ether; the a -phenoxylauric acid is then esterified with n-butanol after conversion into the acid chloride with thionylchloride: (2) a -phenylmercaptostearic acid is similarly prepared from a -bromstearic acid and thiophenol and is then esterified with ethyl alcohol.  Polyhydric and primary, secondary or tertiary alcohols and mercaptans may be used for the esterification, and the following aliphatic acids are mentioned: a -methoxylauric acid, a -ethylthiostearic acid and a -tolythiolauric acid.ALSO:Esters, including thioesters are prepared from hydroxy or mercapto fatty acids which contain at least six carbon atoms and are alkylated, cycloalkylated, aralkylated or arylated at the hydroxy or mercapto group, and hydroxy or mercapto aliphatic compounds containing less than six carbon atoms.

Abstract: 1,013,264. Post-tensioned light-weight concrete structures. SKOVDE GASBETONG A.B. Sept. 6, 1962 [Sept. 14, 1961; Aug. 17, 1962], No. 34166/62. Heading E1V. In the production of light-weight concrete beams, the unreinforced beam or beam sections is/are steam cured and dried, e.g. in an oven, before the beam is post-tensioned. Fig. 2 shows a steel-reinforced beam with end-plates 12, and nuts 15 for adjusting the pre-stressing force as the beam swells again after being dried out. The reinforcement ducts may be pre-moulded or drilled out, and the reinforcement may be steel bars or rods of glass-fibre reinforced synthetic plastics material. In the latter case the reinforcement may be thickened at each end, e.g. conically, or the ends of the rods may be split, and wedges forced into them. The plastics material may be formed around only the centre section of the bundle of glass fibres forming one rod before the rod is inserted into the beam, and the rest added afterwards, or the bundle of glass fibres alone may be pulled through the duct or groove, and the plastics material poured in afterwards.

Abstract: 780,929. Clamp fastenings. HAHN, A. Sept. 2, 1954 [May 15, 1954], No. 34333/56. Divided out of 770,552. Class 44 [Also in Group XXVIII] On appropriate turning of a pin 49, Fig. 1, journalled in lugs of a sleeve 1 a toothed eccentric 43 journalled on an eccentric portion of the pin moves bodily into clamping engagement with a tube 6 inserted in the sleeve 1, any subsequent relative axial movement of the pipe and sleeve causing the eccentric to turn for intensified clamping, the development of excessive pressures being prevented by a housing 61 limiting the eccentric rotation. The eccentric is normally centralized by a leaf spring 62. The pin 49 is turned by its bent end 59 internally or externally engageable by an extension arm and which can move through slightly more than 180 degrees to allow the pin eccentric portion to take up a slightly overcentre position on clamping. The sleeve 1 may be extended to mount a further like eccentric device so that two tubes may be clamped end to end, as for the transmission of liquid or steam. Alternatively the sleeve 1 may mount a second sleeve 41 which may clamp a second tube 35 by such a further like eccentric device 45 or by the tube 6 transmitting the clamping pressure of the first eccentric device to the tube 35 either by direct contactbetween the tubes or, if the sleeve 41, Fig. 4, is turnable on the sleeve 1, by a ring 49<SP>1</SP> - which may have-plain ends or be constructed as described in Specification 770,552. The eccentric 43 has helical teeth curved to fit the pipe 6.

Title: Improvements in or relating to dish washing machines
IPC: A47L15/22
Filed: 1947-12-29
Abstract: 647,232. Dish-washing machines. AKTIEBOLAGET ELEKTROLUX. Dec. 29, 1947, No. 34375. Convention date, July 10, 1943. [Class 138(i)] A dishwashing machine comprises a movable spraying device formed with two groups of jets for washing liquid and rinsing liquid respectively, liquid driving means for the said device and means for automatically shutting-off the washing liquid jets substantially immediately when the other jets are supplied with rinsing liquid, without any appreciable slowing down of the device. A washing liquid jet head 26, and a rinse water jet head formed in two sections 42, Fig. 2 are mounted for rotation together, on the outer end of an arm 25 projecting from a pump housing 22, Fig. 1, rotatable in the sump of a container 10. The pump. housing incorporates a chamber in which is mounted an impeller 20 driven by the shaft 19 of an electric motor 21. The chamber is in communication with the jet head 26 by a spiral channel way 36 and channel ways 54 and 50. A channel way formed by a sleeve 16 concentric with the shaft 19 is connected at 17 to a rinse water supply and said sleeve is in communication with the rinse jet heads 42 by means of a passageway 40 in the arm 25, and through a hollow shaft 27<SP>1</SP> to which both jet heads are secured for rotation. The top of the hollow shaft is also in communication with a chamber in which is fitted a spring controller piston valve 59, by a passageway 70. The bottom of the shaft 27 is fitted with a gear wheel 29 meshing with an idler gear wheel 30 which meshes with a toothed rim 31 rigidly connected to the pump housing. Washing liquid which is heated by an electric element controlled by a thermostat 13 enters the bottom of the pump housing after passing through strainers 12 and 32, and is pumped to the jet head 26 by the impeller 20. The rotary motion imparted to the liquid in the pump chamber is also imparted to the pump housing itself which therefore rotates and causes the jet heads to perform a planetary motion, through the gearing 31, 30 and 29, around the bottom of the container 10. On rinse water being supplied to the jet heads 42 the valve 59 is made to move downwardly against the action of its spring 62 to close the junction of the channel 36 and the channels 54 and prevent washing liquid from reaching the head 26. On stopping the supply of rinse water the valve 59 is liftly upwardly by its spring 62 and thus washing liquid is allowed to pass to the jet head 26. During both washing and rinsing operations the motor 21 continues to drive the impeller 20.

Abstract: 1385716 Laminates LAVORAZIONE MATERIE PLASTICHE SpA 24 July 1972 [10 Aug 1971] 34488/72 Heading B5N A laminate comprising a layer of rigid, closedcell foam thermoplastic at least one of the faces of which is heat sealed to a backing sheet is produced by heating a backing sheet to a temperature above the fusion temperature of the thermoplastic foam and continuously pressing the heated backing sheet into contact with a surface of a layer of rigid closed cell thermoplastic foam so that the heated backing sheet causes fusion of the surface of the foam layer with which it is in contact and the backing sheet becomes bonded to the foam layer without the use of an adhesive. The backing sheet may be of paper, cardboard, fabric, aluminium sheet or plastics film and the foam may be of polystyrene of thickness 1-10 mm. The foam may be made by extruding, e.g. through an annular slit, a heat-softened pressurized mass of polystyrene having dissolved or dispersed therein an expanding agent, e.g. isopentane, drawing it tranversely and longitudinally before or during cooling, optionally slitting, subjecting it to pressure, stabilization of its cells by storing it for at least 24 hours at atmospheric or slightly superatmospheric pressure and then subjecting it to expansion by heating it to a temperature 10-30 C. less than its softening temperature and to quick cooling, e.g. to less than 50 C. by means of jets of cool air. In Fig. 1 foam layer 12 is passed under the action of mutually parallel pairs of chain entrainers 14, 16 between heat radiators 20 so that it increases in thickness and its density decreases, cooled by means of fans 21 and trimmed by knives 22, the cuttings 24 being sent for remelting. Strips of paper 32 and 34 run over arcuate shields 36 and 38 heated by electrical resistances 40 and provided with pressure feet 36A and 38A which press the paper against the foam web. The temperature of the pressure feet may fall progressively in the direction of travel of the laminate to below the melting point of the foam resin and subsequently to below the softening point of the resin. Rollers 42, which may be heated, form a calibrated passage of width less than the thickness of laminate 12A to anneal the bond between the components. The laminate is then heated by infra-red radiators 44 to cause further expansion of foam web 12 while the laminate is kept stretched by the traction exerted by rollers 26, passed between cooled rollers 46 and calibrator rollers 50 each associated with cooling fan 52 and cut into sheets of the desired length by cutting device 54. Shields 36 and 38 may be replaced by one or more pairs of heating rolls.
